Claims

[Scope of utility model registration request]

In a device that controls the transmission torque capacity of a clutch by changing the hydraulic pressure, oil is installed on the large diameter side of the piston so as to communicate with the hydraulic oil chamber formed between the piston and the clutch drum that holds the clutch plate. A passage is provided through a throttle means, and an annular oil reservoir chamber extending from a large diameter side to a small diameter side is formed in the piston, and the oil passage communicates with the oil reservoir chamber, and the oil reservoir is connected to the oil reservoir from the clutch drum. A wet type multiplexer characterized in that a partition wall extending into the chamber partitions the oil sump chamber into a small-diameter, communicating form, and a drain hole is provided in the clutch drum of the oil sump chamber located on the clutch plate side. Board clutch.
